According to Fig. 2, with lower roll I, the gudgeon Ia of II and III, IIa, IIIa (seeing Fig. 3 b) is mounted to can be at mounting 32a, and 33a rotates in the 34a (not Biao Shi 32b, 33b, 34b are positioned on the opposite side of drawing mechanism).Bolt is on sliding

part

35a and 36a respectively for mounting 33a and 34a, and this sliding

part

35a and 36a can be along a bar 37a towards arrow C, D and E, and the direction of F moves.The two ends of this bar 37a are fixed in mounting blocks 38 ' (38 " expression), and this mounting blocks is fixed on the frame 39.

Side by side mobile sliding part 35a, 35b; 36a, 36b can make mounting 33a, 33b; 34a, 34b be respectively along C, D and E, and the F direction moves, and makes lower roll II and III respectively along C thus, D and E, the F direction moves.Correspondingly, the

top roll

13 and 14 that is connected is also respectively at C, and D and E move on the F direction (move mode is not shown).By this method, can change and set roll spacing between the roller group.

Utilize bolt device, stop device or its analog (referring to Fig. 7) to lock this sliding part 35a, 35b; 36a, 36b.

According to Fig. 3 a, utilize a kind of common loop mechanism flowing to right-hand side driving lower roll II and the III that the A direction is seen towards material, the form of this loop mechanism is a profile of tooth belt wheel 40,41 and a cog belt 47.By driving gudgeon IIa, the IIIa place provides the speed gear with different numbers of teeth, can make lower roll II and III have different rotating speeds.Cog belt 47 is a control device of servo motor 19 along direction B (that is, direction) opposite with the operative orientation form of extending to.Utilize form to drive lower roll I at the left-hand side of machine for a loop mechanism of profile of tooth belt wheel and cog belt 47.For this reason, cog belt 47 ' side extends to servo motor 20 from the profile of tooth tep reel 40 at lower roll I place along direction G leftward

In when operation, that is to say when ribbon when the A direction is advanced, cog belt 47 moves along direction G.Cog belt 47 is from the profile of tooth belt wheel 44 that is arranged on the CD-ROM drive motor 19, sequentially the leading block 46 that extend through one profile of tooth belt wheel 45, is smooth, profile of tooth belt wheel 40 (the roller drive pulley of lower roll III), profile of tooth belt wheel 41 (the roller drive pulley of lower roll II), a smooth leading block 42 and a profile of tooth belt wheel 43.Utilize the tooth of this cog belt 47 that this cog belt 47 is meshing with each other with profile of tooth belt wheel 40,41,43,44 and 45.The shiny surface (reverse side) relative with the profile of tooth side is in contact with one another and engages with smooth leading block 46 and 42 in this cog belt 47.Cog belt 47 is around 40 to 46 one-tenth one closed-loop paths of all pulleys.When operation (when ribbon in drawing process when the A direction moves), profile of tooth belt wheel 40,41,43,44 and 45 clockwise rotates, and leading block 42 and 46 rotates counterclockwise.

Profile of tooth belt wheel 40,41 is connected with 33a with mounting 34a in mode rotationally respectively, and leading block 42,46 is connected with 36a with sliding part 35a in mode rotationally respectively.Owing to fixedly connected between mounting 34a and the sliding part 36a, and fixedly connected (for example, utilizing bolt) between mounting 33a and the sliding part 35a, thus lower roll III and II respectively with profile of tooth belt wheel 40 and 41 in one and the leading block 46 and 42 one be connected.Cog belt 47 turns round around pulley 40,46 to symmetrical manner on the one hand with mirror, on the other hand around pulley 41,42 runnings (referring to Fig. 3 b).

Roller is VV (preliminary draft) to the area identification between 13/II and the 14/III, roller to the area identification between 12/I and the 13/II be HV (dominant draft) (a) referring to Fig. 4.According to Fig. 3 a, when needs increased roller to the roll spacing between 13/II and the 14/III, wherein at least one pair roller moved apart another pair roller.For this reason, can be towards right-hand mobile sliding part 35a, this can realize by dual mode:

A) locking of releasing sliding part 35a.Make a pulley for example profile of tooth belt wheel 44 stop operating.This braking can utilize machinery or calutron to realize.As a result, cog belt 47 is just static, and is no longer mobile.Then, for example manually use crank etc. that profile of tooth belt wheel 41 is rotated counterclockwise, inevitably, leading block 42 will clockwise rotate.In this process, the rotation of profile of tooth belt wheel 41 will be converted into sliding part 35a vertically moving along direction C, profile of tooth belt wheel 41 and leading block 42 are rolled this cog belt 47 along the opposing face of static cog belt 47 respectively, thereby a wheel place " shortening " cog belt 47 therein, take turns place's " lengthening " cog belt 47 at another.In turn-up process, the belt length that profile of tooth belt wheel 41 places need is provided by leading block 42.Thus, just lower roll II is moved along direction C by sliding part 35a and mounting 33a.

B) remove the locking of sliding part 35a, and profile of tooth belt wheel 41 is stopped operating.As a result, leading block 42 also must stop operating.Then, utilizing CD-ROM drive motor 19 to produce clockwise rotates.Cog belt 47 just moves along direction G, and similarly, a wheel place " shortening " cog belt 47 therein, take turns place's " lengthening " cog belt 47 at another.Needed belt length is actually by the belt length between profile of tooth belt wheel 43 and the pulley 42 between the profile of tooth belt wheel 40 and 41 provides.Thus, the rotation of profile of tooth belt wheel 44 and cog belt 47 mobile is converted into sliding part 35a vertically moving along direction C.As a result, the lower roll II that is installed on the mounting 33a (it is connected rigidly with sliding part 35a) also correspondingly moves along direction C.

In fact, common situation is according to Fig. 4 a to 4d, at first to adjust preliminary draft district VV, and then adjust main drawing area HV.Under the situation that draw zone VV and HV all shorten, sliding part 36a moves to position shown in Fig. 4 b from position shown in Fig. 4 a along the arrow E direction.As a result, the roll spacing of preliminary draft district VV is by " a is for foreshortening to " a ' ".Then, according to Fig. 4 c, utilize a bridgeware 50 fixedly connected sliding part 36a and 35a.At last, according to Fig. 4 d, fixedly connected sliding

part

36a and 35a shift to position shown in Fig. 4 d from position shown in Fig. 4 c along arrow E and C.As a result, the roll spacing of main drawing area HV foreshortens to " b ' " by " b ".Under the situation of lengthening preliminary draft district and main drawing area, adopt another set of corresponding step, that is, interconnective sliding

part

35a and 36a move (referring to Fig. 2) along arrow F and D direction, and the result just makes main drawing area HV lengthening.Then, remove being connected of sliding

part

35a and 36a and bridgeware 50.At last, sliding part 36a moves (referring to Fig. 2) along arrow F direction, and the result just extends preliminary draft district VV.

For the ribbon in the drawing mechanism 25, should note to such an extent that be under the situation that shortens draw zone VV and HV, in moving process, roller is to the ribbon 5 of 14/III upstream according to Fig. 4 a and 4b ^IVWill be a bit of to the elongation of B direction, but with respect to conveying

roller

7,8 and roller the spacing between the 14/III is grown (approximately 1.5m), and this elongation is not remarkable.Under the situation that shortens preliminary draft district VV, can not form the ring that sink in the preliminary draft district VV because roller interconnects by cog belt 47 14/III and 13/II, in moving process, each of two roller centerings in other words two pairs all be rotating.On the contrary, under the situation that shortens main drawing area HV, ribbon 5 " can form a sagging ring, utilize main motor 20 can stretch to 12/I or the stretching ribbon 5 that should sink along operative orientation A live-rollers ".Under the situation of lengthening draw zone VV and HV, the first step, roller along B direction backward rotation, " forms a sagging ring thereby make ribbon 5 wittingly to 12/I.Then, move interconnective sliding

part

35a and 36a along direction D and F, with lengthening main drawing area HV, in this process, the sagging ring of having a mind to form is stretched again or is stretching.At last, remove the connection of bridgeware 50, move sliding part 36a along the F direction.Because the above-mentioned input lower roll of having mentioned and middle lower roll interconnect by cog belt 47, the interior ribbon 5 of preliminary draft district VV ' length remain unchanged.Roller is to the ribbon 5 of 14/III upstream ^IVMay compress slightly, but with respect to ribbon 5 ^IVDrawing-off and structure, this compression is not remarkable.

Fig. 5 a, 5b have represented the structure that causes sliding

part

36a and 35a to move.Roll spacing in the preliminary draft district VV by " a " (it is " a " that Fig. 5 a) extend " (Fig. 5 b).Sliding

part

36a and 35a move in succession along arrow E and C direction respectively.Move and to be achieved in that braking profile of tooth belt wheel 40 or to utilize a stop valve etc. to fix this profile of tooth belt wheel 40 that start CD-ROM drive motor 19 then, cog belt 47 will move thus.Along with continue moving of cog belt 47, sliding

part

36a and 35a will be according to Fig. 4 a, 4b and then according to Fig. 4 c, and 4d moves.
